ONBOARD DIAGNOSTIC
SYSTEM
Operation
The OBD (Onboard Diagnostic system)
carries out a continuous diagnosis of the
components of the vehicle related to
emissions.
It also alerts the driver of when these
components are no longer in peak
condition by switching on the
warning
light on the instrument panel (see
“Warning Lights And Messages”
paragraph in this chapter).
The aim of the OBD system (Onboard
Diagnostic) is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace damaged
components
The vehicle also has a connector, which
can interface with appropriate tools, that
makes it possible to read the error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnosis. This check can be carried out
by your authorized dealer.
Note: After eliminating a fault, to check
the system completely, your authorized
dealer is obliged to run tests and, if
necessary certain road tests.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an
Onboard Diagnostic system (OBD II) and
a connection port to allow access to
information related to the performance
of your emissions controls. Authorized
service technicians may need to access
this information to assist with the
diagnosis and service of your vehicle and
emissions system.
Warning!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to diagnose or
service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access,
information stored in your vehicle systems,
including personal information.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal
requirement to pass an inspection of your
vehicle's emissions control system.
Failure to pass could prevent vehicle
registration.
For states that require
an Inspection and
Maintenance (I/M), this
check verifies the
“Malfunction Indicator
Light (MIL)” is functioning and is not on
when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready.
The OBD II system may notbe ready if
your vehicle was recently serviced,
recently had a dead battery or a battery
replacement. If the OBD II system should
be determined not ready for the I/M test,
your vehicle may fail the test.
Your vehicle has a simple ignition
actuated test, which you can use prior to
going to the test station. To check if your
vehicle's OBD II system is ready, you
must do the following:
1. Cycle the ignition switch to the ON
position, but do not crank or start the
engine.
Note: If you crank or start the engine,
you will have to start this test over.
